Popis:	The development of blockchain applications increased the demand for blockchain performance. Among the attempts of many blockchain scale-out solutions, sharding can improve performance and reduce the storage requirements of each node. Sharding enhances the throughput of the entire blockchain. Most sharding solutions have a fixed number of shards. We propose Wider chain with sharding by account. The number of shards is increased to unlimited. Meanwhile, Wider combines the idea of rollup and retains the main chain to confirm the status of the subchains. This design can avoid the Proof of Work computing power being scattered to the subchains and ensure the security of the blockchain. Comment: 12 pages, 7 figures
